The major categories of pain-acute and chronic
Acute pain is normally the result of an illness, some sort of injury or occurs after surgery. This type of pain causes the body to automatically stop what you are doing in an effort to protect it from further harm. This is due to the tissue damage that causes the pain receptors to respond.
Unlike chronic pain, acute pain can be pinpointed. You know exactly where you hurt and can put your fingers in the area where it hurts. Fortunately, this kind of pain generally subsides with time and gradually goes away.
Chronic pain by definition usually lasts six months or longer. It may stem from a chronic joint condition caused by arthritis, peripheral neuropathy or it could be the residual effects of an accident, infection, tumor or surgery that has damaged the nerves. In other cases, the cause of the pain is not understood because there is no evidence of a disease or damage to the tissues that would trigger it.
See your doctor and take care of the problem.
